An active filter is connected in parallel to a load, the active filter including a second rectifier group with at least one rectifier and a pulse bridge connected to an output thereof. A second-order low pass filter has a clock inductor, a capacitor, and an RC damping, the clock inductor being connected located at an output of the pulse bridge. A voltage of the at least one rectifier of the first controllable rectifier group and a voltage of the active filter in an open and closed loop is controlled, a first controlled system controlling a current of the at least one rectifier of the first controllable rectifier group of the power supply system in open and closed loop via a first controller by an output-side open- and closed-loop controlled variable, and a second controlled system of a second controller for a load current and a subordinate controller for a load voltage controlling the active filter in open and closed loop using a feedforward control variable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generation of highly accurate and highly dynamic direct currents from a rectifier group and an active filter which is connected in parallel with the load for smoothing purposes","description":"A power supply for generating temporally specifiable, open- and closed-loop controlled current paths includes a first controllable rectifier group that includes at least one rectifier having a smoothi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537576","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
